Objectives: Increasing salt preferences with age are said to increase preferences of salty foods, thereby leading to greater sodium consumption, which has further implication for hypertension. This study examined the link between preference of salty taste and dietary factors and health-related risk factors in Korean elderly people. Methods: We studied 312 elderly individuals aged > 65 years (male, 100 and female, 212). With each subject, pleasant concentration of NaCl was estimated using the sip-and-spit method. Dietary habits, food preferences, consumption frequencies, anthropometric and biochemical assessment were assessed. Results: The pleasant salt concentration was significantly increased in individuals older than 75 years (p < 0.05). Subjects who liked high concentration of salt showed significantly higher preferences for salty foods (p < 0.001). Results showed significant effects (p < 0.01) of fruit & fruit juice consumption frequencies, MNA (mini-nutritional assessment), cognition score, BMI, body fat %, waist circumference, arm circumference, calf circumference, vitamin D level that subjects who likes low salty taste were higher than subjects who likes high salty taste. Conclusions: The preference for salty taste in the elderly was not correlated with hypertension. But, increased preference for salty taste with age and increased salty food preferences may result in higher sodium consumption. Therefore, nutritional education regarding lowering salt preference and favorable behaviors of low-salt diet is needed to improve the quality of life in the rural elderly.

Volatile compounds, isolated from Chopi (Zanthoxylum piperitum A.P. DC.) using steam distillation, were analyzed by gas chromatography/mass spectrometry-olfactometry (GC-MS-O). Forty-six volatile compounds, consisting of 12 hydrocarbons, 8 aldehydes, 5 esters, 12 alcohols, 4 ketones, 4 oxides and 1 acid, were tentatively identified from the essential oil of Chopi. Unidentified compounds constituted 7.2% of the total peak area. Limonene was the most abundant compound, followed by geranyl acetate, citronellal, cryptone and ${\beta}$-myrcene. In addition, aroma-active compounds, in particular citronellal and limonene, which are related to the citrus and Chopi flavors of Chopi essential oil, were detected. The aroma of Chopi essential oil had a score of 4.8 on the preference test (neither like nor dislike) and a score of 5.97 on the intensity test (slightly strong) using the 9-point hedonic scale.

Especially, purchase factors of seaweeds was conducted only in married females (n = 353). The subjects are composed of 46.5% male and 53.5% female. Regional distribution of subjects was found to be 16~17%, with highest ratio in the age bracket of 20~29 years old. Proportion of students, at 29.8%, was the highest ranking occupation of the subjects. Preference score of seaweeds by region was highest for laver followed by brown seaweed and sea tangle. In terms of preference by gender, female subjects displayed higher preference score for green laver (p < 0.01), seaweed fusiforme, brown seaweed, sea tangle (p < 0.001) than the male subjects.

This study was conducted to investigate the nutritional status and factors related to dislike of vegetables in the students who avoid eating vegetables in elementary school. The subjects were classified into VDG (vegetable dislike group, 75 children) and control group (69 children) by amount of vegetable left in school feeding. The survey included the items of demographic characteristics, dietary behaviors, nutrition knowledge, food preference, reason for dislike of vegetables and nutrient intake of the subjects. Dietary behavior and nutrition knowledge scores of control group were higher than those of VDG. The average score of food preference was 4.9 and 4.7 in control and VDG groups respectively. The preference score of root vegetables was the lowest in subjects. In the view of nutrient intake, the calorie intake of control group was higher than that of VDG. Protein intake of control and VDG was enough as compared with their RDA. Except vitamin E, most nutrient intake of control group was higher than that of VDG. VDG consumed lower calorie, vitamin A, vitamin $B_2$, vitamin C, Ca, P, Fe and Zn than control group. The scores of the dietary behavior and nutrition knowledge in the subjects were positively related to the status of some vitamins and minerals intake. These results show that the scores of nutrition knowledge and dietary behavior of VDG were lower than those of control, causing low intake of vitamins and minerals such as vitamin A, Ca and Fe.

The study surveyed the dietary behavior, food intake, and food preference for breakfast of elementary, middle, or high school students, a total of 354 boys and 305 girls. The students skipped breakfast due to no appetite, followed by no time. Elementary school students ate grains and potatoes more often than middle or high school students(p<0.05), and bap was the most frequently consumed cereals, with juk and tteok as the least. High school students ate meat, ham, sausage and boiled fish cake (eomuk) more often than the elementary or middle school students(p<0.05). Middle school students ate milk and dairy products as well as vegetables and fruits more often(p<0.05) than other foods. Preference for fish and fresh vegetables and salad was significantly high in middle school students. The score of dietary behavior was the highest in elementary school students, followed by middle and high school students(p<0.001). As the students advanced to the upper grade schools, breakfast skipping increased, with lowered dietary behavior scores. The results suggest that a variety of breakfast menus and recipes should be developed at home and schools by considering the preference of students in order to reduce breakfast skipping and to improve their satisfaction with breakfast.

The oil most commonly used for deep-fat-frying was soybean oil followed by com oil. Proper frying temperature was determined by dropping salt or food coating materials into the oil. Oil color was used as a parameter for determining the life of frying oils by 81.2% of the respondents. Most of the respondents appealed to use oils one more time after filtering. For the disposal of used frying oil, 65.7% of the respondents used some kinds of absorbing papers; 16.1% made soaps and 10.7% discarded into a sink.
